@mhoghrab I changed the copyright notice on top of the *.cc and *.h files in the commit fd9e259. Your authorship (see last line below) is still acknowledged but since the code ends up in the repository it needs to contain the standard header and be distributed under Apache 2.0. I assume that is OK for you?
